->''"Green and black,\\
Queen and priest,\\
Trace of rouge,\\
Face of beast,\\
Faces -\\
Take your turn, take a ride\\
on the merry-go-round\\
in an inhuman race!"''
-->-- ''Theatre/ThePhantomOfTheOpera'', "Masquerade"

Want to show off just how rich, elite, and extravagant your [[BlueBlood upper class]] is? Have them celebrate everything with a Masquerade Ball. With bizarre masks and elaborate GorgeousPeriodDress, everyone's identity is sufficiently obscured for any number of misunderstandings. Either Horror or HilarityEnsues.

For really grand scale masquerades, the writers may include festivities where the entire city [[GorgeousPeriodDress dresses up in grand costumes]], a la Carnival/Mardi Gras. Which maximizes the chance for confusion and mingling with people one would normally never know. Hard to avoid in [[ItsAlwaysMardiGrasInNewOrleans New Orleans]] and Venice.

A popular 19th-century setting, due to, as Website/TheOtherWiki puts it, "both to their popularity at the time and to their endless supply of plot devices." To wit: Mistaken identities, untraceable murderers, believing something is AllPartOfTheShow, a normally-costumed character hiding in [[ForHalloweenIAmGoingAsMyself plain sight]], (or mocked for their [[YourCostumeNeedsWork poor quality costume]]) and one of the attendees' masks being revealed to be their ''[[NotAMask actual face]]''. [[DecadentCourt A court is a... difficult place.]]

The refinery on top of the sheer trope goldmine that is the Masquerade Ball is the convention of using aliases to go with the masks. Historically, that can free participants to indulge in era-appropriate 'scandalous' behaviors -- and also make a good opportunity for the uninvited to crash. Watch out for the mass robbery by the PhantomThief and ClassyCatBurglar, and hope there's a [[UsefulNotes/TheGoldenAgeOfComicBooks Golden Age]] SuperHero around somewhere. CharityBall often combines with the theft, to give the thieves a good way to infiltrate.

A modern costume party has some of the potential for this, especially if there are disguises abounding. If it's an ''actual'' Masquerade Ball in a modern setting, expect at least one guest to bring out the ''Theatre/RomeoAndJuliet'' quotes. If FanService is desired, the modern costume party has a great advantage: Whereas the nineteenth century believed in modesty, the twenty-first century is a time in which you can expect plenty of [[SexyWhateverOutfit Sexy Whatever Outfits]].

Even those who vainly deny that EveryoneIsJesusInPurgatory may grudgingly admit the social metaphor inherent in the Masquerade Ball.

A SubTrope of DancesAndBalls and a period-specific Sub Trope of ThemedParty.

Has nothing to do with the {{Masquerade}} (and can actually mean a break from it, such as ForHalloweenIAmGoingAsMyself).

!!Examples:

[[foldercontrol]]

[[folder:Anime & Manga]]
* In ''Anime/TheBigO'', Schwarzwald rigged it so that the masks would eventually explode.
* ''Anime/HelloSandybell'': When Marc and [[AbhorrentAdmirer Kitty]] are engaged, they have one. Sandybell disguises herself as a cookie vendor to sneak in and dance with him.
* ''Anime/IsabelleOfParis'' begins with Isabelle preparing for one, as in French society it's customary for every woman to debut at one.
* Frequent in ''Anime/LaSeineNoHoshi'', which takes place during UsefulNotes/TheFrenchRevolution. Out of all the nobles, Marie Antoinette is frequently called the most beautiful woman at the ball.
* ''Anime/LupinIIIDragonOfDoom'' features one hosted by Chin Chin Chow on his luxury cruise ship. Lupin and Jigen (dressed up as a vampire and a werewolf, respectively) managed to attend the ball through forged invitation cards, whilst Fujiko (dressed as a cowgirl) really was invited.
* In ''Manga/MoriartyThePatriot'', Albert and Irene meet at one of these in ''The Scandal in the British Empire'' to converse discreetly and share information, while showcasing the excesses of the aristocracy.
* ''Manga/TheRoseOfVersailles'' works at least one into the plot, with Marie Antoinette sneaking out of Versailles to attend one in the city where she meets Fersen, kicking off her major romantic subplot.
* ''Franchise/SailorMoon'': Both the [[Manga/SailorMoon manga]] and [[Anime/SailorMoon first anime]] feature Usagi attending a masquerade ball held at the D Kingdom's embassy in order to find out if the royal family's treasure is the [[MineralMacGuffin Silver Crystal]] and if Princess D is actually the Moon Princess that they are looking for. The scene is more significant in the manga as [[spoiler: Mamoru and Usagi both reveal that they have memories of each other in a past life]] at this event. Naturally, the two of them also share a dance together.
* The second arc of ''VisualNovel/UminekoWhenTheyCry'' ends with a demonic twist on one of these [[spoiler:celebrating the resurrection of the witch]]. Everyone except for Beato wears [[{{Mook}} goat head masks]]. The halls are decorated with [[ButterflyOfDeathAndRebirth golden butterflies]]. [[ImAHumanitarian There is plenty to eat and drink.]]
* ''Anime/UruseiYatsura'': The Mendo family has a masked ball every year. This is a rather psychotic pun as the word for "ball" (as in party) can also mean "combat challenge". Which is what it was - all the participants put on masks and attack each other, taking out their frustrations in anonymity. (Then the monk Cherry shows up, having mistaken the Japanese phrase "masked ball" for "grape harvest" and wants to pick grapes ... Creator/RumikoTakahashi likes puns.)
* In ''Manga/VampireKnight'', a Masquerade ball is held in Chapter 87 of the manga, with Zero and Yuki sharing a masks-on kiss, away from the crowd. You'd expect these types of scenarios in a world filled with aristocratic bishonen and bishoujo vampires having a social structure heavily resembling a monarchy.
* ''Manga/{{Vassalord}}'': In vol. 4, [[spoiler: Rayflo sends Charlie a note to attend a masquerade so they can meet up. They quote Theatre/ThePhantomOfTheOpera at each other and eventually a fight between Barry and Charlie breaks out.]]
* ''Anime/VoltesV'': As if you needed any more cues that the [[HornedHumanoid Boazanians]] are a FantasyCounterpartCulture to UsefulNotes/{{France}}, in General Dange's flashback, the nobles are shown having a MasqueradeBall, while the commoners are excluded and forced to do hard labour.
* ''Anime/WolfsRain'': The climax has the villainous [[AristocratsAreEvil Nobles]] gather to celebrate their slightly insane plan with such a party.

* In both ''ComicBook/DetectiveComics'' #359 and ''ComicBook/BatgirlYearOne'', Barbara Gordon first created the ComicBook/{{Batgirl}} outfit as a costume for a party (and to annoy her father in the updated story). When the party was crashed by supercriminals, she responded to the crisis like a costumed crimefighter rather than a costumed partygoer (Which Bruce Wayne did, seeing as he was in a clown outfit at the time), starting her journey to become a member of the Bat-Family.
* Happens once in a while in ''ComicBook/{{Diabolik}}''. On one occasion [[SympatheticInspectorAntagonist Ginko]] complained that the terrorists that were the villains of the story could have infiltrated it by just wearing a mask... And not only their leader ''does just that'', but ''[[VillainProtagonist Diabolik and Eva are there too]], wearing costumes over their [[LatexPerfection perfect masks]]''.
* ''ComicBook/FireflyTheSting'': The commitment day ceremony is a lavish event that takes place in the convent. All the attendants dress fancily and wear white masks that leave only their eyes uncovered.
* Featured in the ''WesternAnimation/{{Gargoyles}}'' comics by SLG. A costume party is held on Halloween at the Xanatos building- where the gargoyles fit right in and Elisa is dressed like Princess Jasmine. (She likes Disney Princesses for some reason.) Meanwhile, Fox and David Xanatos are attending a masquerade at the White House.
* In ''ComicBook/LadyMechanika'' #4, Mechanika infiltrates a masquerade ball being thrown by her [[AristocratsAreEvil nemesis Lord Blackpool]] by [[MuggedForDisguise knocking out a female guest and stealing her costume and invitation]].
* ''ComicBook/SensationComics'': The first time Countess Draska Nishki shows up she throws a Masquerade Ball which ComicBook/SteveTrevor is instructed to attend to act as a {{honey pot}} even though Steve already knows Nishki is expecting him. The Holliday Girls attend the party as well and one of them dresses as Franchise/WonderWoman and ends up mistaken for the real thing when she's spotted helping a drugged Steve escape.
* ''Franchise/TheSmurfs'' hold various types of masquerade parties in the comic books, although, in a one-page gag, most of the Smurfs end up going to one party as Papa Smurf, except for [[ForHalloweenIAmGoingAsMyself one Smurf who seemingly went as himself]] -- only it turns out to be ''Papa Smurf in a costume''.
[[/folder]]

[[folder:Comic Strips]]
* ''ComicStrip/ModestyBlaise'': In "Our Friend Maude", Modesty and Willie take advantage of an 18th century-themed masquerade ball being held by a group of {{arms dealer}}s to spy on them. They have to improvise madly to come up with costumes and invitations in time.
[[/folder]]

[[folder:Fan Works]]
* ''Fanfic/TheFundamentalEssenceOfVillainy'': ''Masquerade'', as the title would suggest, takes place at a charity masquerade ball.

* In ''Film/{{Ridicule}}'', a scorned lover attempts sabotage at an elegant costume ball in pre-Revolutionary France.
* The film ''Film/StartTheRevolutionWithoutMe'' (a humorous account of the French Revolution) has a hilarious send-up of this type of party. Even though it's technically not a Masquerade Ball, everyone still wears elaborate court dress--except for King Louis the XVI, who arrives in an elaborate chicken costume. (Apparently his devious wife told him it was [[ItsACostumePartyISwear supposed to be a costume ball]] and then "changed her mind" without telling him.) There's also plenty of intrigue, spying, and backstabbing going on as the ball patrons exchange secret notes with each other--so many notes in fact, that the ''entire floor'' gets covered with them.
* In the musical number/flashback "Poor Thing" in ''Film/SweeneyToddTheDemonBarberOfFleetStreet'', Lucy Barker, the wife of the title character, is lured to the house of Judge Turpin by Beadle Bamford, who tells her that the Judge is remorseful about what he did to her husband and wants to see her at his mansion. Unknown to Lucy, the Judge has thrown a wild masked ball at the mansion that is well underway when Lucy arrives. Lucy, confused and disoriented by the sights and sounds of the party and from the number of drinks she has at the place, winds up in the hands of Judge Turpin himself, who is anything but remorseful and has used this party as a means to trap and rape her:
-->'''Mrs. Lovett:'''\\
She wasn't no match for such craft, you see,\\
and everyone thought it so droll.\\
They figured she had to be daft, you see.\\
So all of them stood there and laughed, you see.\\
Poor soul!\\
Poor thing!

[[folder:Literature]]
* ''Franchise/{{Batman}}'': Many of the short story collections feature this. A few times Bruce Wayne shows up in a Batman costume. How silly!
* ''Literature/TheButterflyBallAndTheGrasshoppersFeast'': Some, but not all, of the guests attend the ball in masks. These include a fox in a [[CommediaDellArte Punchinello]] costume, a snail who wears a bright smiling mask [[ShyShelledAnimal to hide his shyness]], and another fox who is wearing a rabbit mask and sitting with a rabbit in a fox mask.
* ''Literature/{{Discworld}}'':
** Referenced by [[TheGrimReaper Death]] explaining why he appeared at a summoning ritual with a cocktail and a sausage-onna-stick. [[foldercontrol]]

[[folder: "The party's nice, but I expect it'll all go downhill after midnight. It's when [[For Halloween I Am Going As Myself they think I'll be taking my mask off. ]]
"]]
** ''Literature/WitchesAbroad'' also includes Death apparently wearing a carnival mask, and in ''Literature/{{Maskerade}}'' he actually does (along with the full ''Red Death'' ensemble), with the shock coming when he ''does'' take it off.
** In ''Literature/WitchesAbroad'', the story of [[strike:Cinderella]] Emberella is done at a masquerade ball. The Witches use this to switch the poor scullery girl with one of their own.
** The Literature/{{Discworld}} novel ''Literature/{{Maskerade}}'' is an AffectionateParody of ''Theatre/ThePhantomOfTheOpera'', complete with [[NeverMessWithGranny Granny Weatherwax]] and [[MagnificentBastard Nanny Ogg]], rural Lancre witches who have no concept of how to behave in high society, dressing up this way and attending an opera performance. This goes about as well as could be expected given the witches concerned.
* ''Literature/TheDresdenFiles'': Harry Dresden gets invited to a vampire masquerade ball in the third book. It's a trap, of course, and he knows it. So he declares his opinion on the subject by showing up in the cheesiest vampire costume ever.
* ''Literature/EllaEnchanted'': The ball at the end is a masked affair, which is convenient for Ella since in this Cinderella retelling the prince already knows her well enough to recognise her unmasked (not to mention her stepfamily). In this case, most of the guests don't wait until the end of the night to unmask, since the event is about introducing the prince to eligible young ladies, and said young ladies want the prince to be able to see how beautiful they are.

* ''[[Literature/TheGoldenOecumene The Golden Age]]'': Opens with a masquerade season to celebrate a once-in-a-millennium holiday.
* ''Literature/HeraldsOfValdemar'': Queen Selenay, partly as a way to see if Prince Thanel of Rethwellan is truly serious about her, holds a masquerade party after the year of mourning for her father is up. She and her eleven ladies-in-waiting dress up as the identical-looking Moon Maidens from Rethwellan legend. Thanel, who is costumed as the Moon Prince, is able to pick Selenay out due to the rose she was wearing at her belt and proposes marriage, which she happily accepts and the two announce their betrothal at the time of unmasking. Too bad things went downhill after the wedding.
* ''Literature/{{Incarceron}}'': The beginning of the climax to ''Saphique'' takes place in a Masquerade Ball.
* ''Literature/TheKingInYellow'': Very obliquely mentioned in an excerpt from a scene of the eponymous BrownNote [[ShowWithinAShow playscript-within-the-book]].
-->CAMILLA: You, sir, should unmask.\\
STRANGER: Indeed?\\
CASSILDA: Indeed it's time. We all have laid aside disguise but you.\\
STRANGER: [[NotAMask I wear no mask.]] \\
CAMILLA: ''(Terrified, aside to Cassilda.)'' No mask? No mask!
* ''Literature/KushielsLegacy'': Frequently feature elaborate masked balls, usually at the winter solstice; however, the trope is averted in that most people's identity isn't really concealed all that effectively. It's an effective plot device for forcing characters together, however.
* ''Literature/TheManWhoWasThursday'': Ends with one.

(Her stepsisters are dressed up as historical personages Empress Josephine and Madame de Pompadour, while her stepmother is the Queen of the Night from ''Theatre/TheMagicFlute''.)
* ''Literature/TheReynardCycle'': The opening chapter of ''Reynard the Fox'' revolves around the titular character taking advantage of a masked ball in order to commit his latest heist. In a nod towards the series' [[BeastFable origins]] all of the guests are dressed in costumes that resemble the animals of their heraldry (Lord Chanticleer, for instance, is dressed up as a bantam rooster.)
* ''Literature/TheRoyalDiaries'': Masquerades pop up occasionally.
** UsefulNotes/HenryVIII loves these types of balls so Elizabeth has attended a few. She notices unmarried couples taking advantage of the disguises to sneak off together for some...ahem, fun.
** Catherine is quite puzzled because the Russian tsarina Elizabeth prefers balls where people dress as the opposite sex.
** A masquerade plays a key role in Mary, Queen of Scots's story: [[spoiler: her music teacher Signore Marcelline was making unwanted advances on Mary Livingstone, threatening to denounce her as a whore if she tried to expose him. The Marys figure out what happened when he attacks Mary Beaton instead, being unable to tell them apart because of the disguises they wore.]]
%%* German author Spoerl once had a ball in one of his stories. The narrator/protagonist meets a girl there and wants to get closer. But when midnight is near, she suddenly wants to leave. He doesn't want to let her go, follows her, and takes off her mask. To see to his shock that she has a disfigured face.

* ''Literature/ASongOfIceAndFire'': The Free City of Braavos was founded as a refuge by escaped slaves from the Valyrian Freehold, and for its first century-plus the location and nature of the city was kept carefully hidden. Every year since the public declaration of their city's existence, the inhabitants of Braavos celebrate this event with ten days of feasting and masked revelry.
* ''Swan's War'': The climax of the first book of the trilogy is a masked ball with such an abundance of plotting, provocation, and foreshadowing that it defines the evenings of both following books.
* ''Turntables of the Night'': Creator/TerryPratchett does a take on "Literature/TheMasqueOfTheRedDeath" in this short story, set at the modern-day ultra-mundane version of the Masquerade Ball; a small town Hallowe'en disco. Everything goes well at first, everyone dancing around in stupid masks and costumes until a man in a black rhinestone suit, platform shoes, and a skeleton mask arrives...
* ''Literature/XWingSeries'': Variation on the planet Adumar. The perator (king) of Cartann puts on a mask at royal balls which makes it socially acceptable for others to treat him as just another guest, even though everyone knows it's him.

All the band members, in the form of one werewolf (who continually shapeshifts between all six without anyone noticing), tracks a woman in a red dress to a masquerade ball, infiltrates them, seeking her out by scent (he/they sniffs various women's shoulders, searching for her), culminating in cornering her in a bedroom, for a fetish / horrific scene in which six wolf heads burst from his body as they kiss. The wolves escape as the partygoers try to catch them, and the woman is implied to have become a Werewolf as well.

* [[https://vignette.wikia.nocookie.net/lalaloopsyland/images/5/57/Confetti_Carnival.PNG/revision/latest?cb=20130724040534 Confetti Carnivale]], a ''Toys/{{Lalaloopsy}}'' doll, is styled around the masquerade ball. She wears an extravagant gown and comes with a black cat mask.

* In the retro-SteamPunk ''VideoGame/{{BioShock|1}}'', many of the splicers are wearing party masks, as there was a 'ball' at about the time they went mad.
** They also use them to hide how disfigured their faces now are.
** Some of them have been wearing the masks so long that their faces have deformed in the pattern of the mask's interior...
* The final case of the Wolf Street district in ''VideoGame/CriminalCaseMysteriesOfThePast'' takes place during the aftermath of a masquerade ball that the victim and most of the suspects attended.
* In ''VideoGame/{{Dishonored}}'', one of the missions takes place at a masquerade ball party. You can, if choose to do so, [[ForHalloweenIAmGoingAsMyself infiltrate as a guest with your own mask]], widely known as a famous assassin's icon, though this will be seen as a flashy and provocative innocent costume.
* In ''Franchise/DragonAge'', the ruling class of the Orlesian Empire have these fairly frequently. The player attends one in ''VideoGame/DragonAgeInquisition'', although they and their associates go unmasked. Iron Bull, a professional spy, notes that the masks are only really good for fashion statements, as they don't offer protection or hide your expression. Vivienne, who's well-versed in Orlesian politics, gives a more detailed explanation.
-->''We all wear masks, my dear. Not just the people in Orlais. Who you are as a son / daughter, a lover, a friend are very different people from the Inquisitor and the Herald of Andraste. Orlesians codify this truth, make it visible.''
* Lord Fain of ''VideoGame/{{Lusternia}}'' has an aesthetic that mixes Masquerade Ball and ChessMotifs. Appropriately, his appearance is an extended ShoutOut to "Literature/TheMasqueOfTheRedDeath", right down to his title ("The Crimson Masque") and his [[spoiler: [[NotAMask actual lack of a mask]]]].
* In ''VideoGame/{{Morpheus}}'', the guests of the ''Herculania'' yacht had one, where Belle Swan performed "Salome's Seven Veils". Her daughter, Claire Moon tried to [[ThrowingOffTheDisability dance off her disease of polio]] after being healed by Jan Pharris' Neurographicon, but it only lasted for a few seconds. Then things went awry when Jan's [[NightmareFace ghoulish facial features]] reappeared.
* Such a ball is the reason the guests, wearing ornate masks, are visiting the titular casino in ''VideoGame/TheSexyBrutale''.
* Creator/{{Infocom}}'s third mystery, "VideoGame/{{Suspect}}", was set at a costume party. The hostess is murdered with part of the protagonist's costume, making the protagonist... well, as the title implies, the suspect.
* ''VideoGame/TheLegendOfHeroesTrailsInTheSky The 3rd'' opens with Kevin Graham attending a masquerade ball being hosted by Hermann Conrad of the Reinford Group. It makes a perfect cover for Kevin, the Heretic Hunter of the Septian Church, to break into Conrad's room and reclaim the artifact that Conrad has been using to gain power and influence, one which lets him tell lies convincingly.

* ''VisualNovel/TheArcana'': Before his death, [[TheCaligula Count Lucio]] would throw an extravagant Masquerade party every year for his own birthday, which any citizen in Vesuvia was permitted to attend.

* Webcomic/TheBugPond: The chapter, [[http://bugpond.awgosh.com/post/73562336490/a-new-bigger-than-ever-bug-pond-story-will-start Masquerade Mayhem]] centers around a masquerade ball.
* ''Webcomic/GirlGenius'': Martellus throws a party in Paris to announce himself as Storm King and Colette is able to convince him and his sister to make it a masquerade which makes it very easy for Tarvek to be at the party without being recognized and killed by Martellus, or any of the other many attendees [[https://www.girlgeniusonline.com/comic.php?date=20170201 who would likely try.]]
* The first arc in the webcomic ''Webcomic/ILoveYoo'' is a masquerade ball.
* Since ''Webcomic/PeriTale'' is about the eponymous Periwinkle trying to fulfill a standard fairy tale, a big part of the plot is actually about getting Vallery to attend a fancy masquerade ball, supposedly to meet her "prince."
* The first arc of ''Webcomic/TheWolfAtWestonCourt'' focuses on Nova’s goal of sneaking into a masquerade ball and forcing Loup to make a dress for her.

[[folder:Western Animation]]
* The episode "Heart of Tarkon" of ''WesternAnimation/AdventuresOfTheGalaxyRangers'' has Doc crashing one of these and using the opportunity to turn on the charm with Maya. Maya is not fooled by his identity in the slightest, [[GiveGeeksAChance but is surprised at how charming he can be]].
* ''WesternAnimation/{{Mirthworms}}'': The plot to the 1987 special "A Mirthworm Masquerade". Bert Worm is planning to go with Crystal Crawler to a local masquerade ball; Bert's costume is a hat, cape, mask, and sword. However, Bert's plans are disrupted by the villainous Wormaline Wiggler, who wants to use the ball to further her own power.
* ''WesternAnimation/RazzberryJazzberryJam'': In “Phantom Of The Jam”, the Jazzberries rehearse for one but must contend with the legend of a ghost who supposedly shows up to haunt any masquerades thrown in the House Of Jam. [[spoiler:The ghost is real, and he’s actually a nice guy who is able to perform with the Jazzberries in the ball.]]
* An episode of the first ''[[WesternAnimation/TeenageMutantNinjaTurtles1987 Teenage Mutant Ninja Turtles]]'' cartoon revolves around a high-class masquerade ball April attends (and looks [[SheCleansUpNicely shockingly stunning]] in her evening gown). She brings the Turtles with her, thinking it'd be fun and ironic. Over the course of the episode, she is [[MistakenIdentity mistaken]] for a similarly-dressed European princess and kidnapped, and when security orders everyone to take off their masks, the Turtles are in an obvious bind.

* The assassination of King Gustav III of Sweden occurred at a masquerade hosted by the King. The assassin was not recognized, but dropped his pistol at the scene, and, thanks to some very fine detective work, the entire conspiracy was unearthed and the involved arrested within a week. The incident was used as a plot for two different operas (see above).
